Filed: 2002-12-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a manufacturing method by which the diameter of metal-containing fine particles is made smaller and the particle size distribution thereof is made narrower.  <P>SOLUTION: A W/O (water in oil) type emulsion is prepared by dispersing an aqueous solution containing a metal or hydrous colloid containing the metal in a flammable liquid by using an ultrasonic homogenizer.

By this manufacturing method, the particle diameter of the produced metal-containing fine particles is remarkably reduced to several tens of nanometers and the particle size distribution is made drastically narrower. Thus the manufacturing method is very useful for manufacturing, for example, yttrium oxide fine particles as a phosphor for a plasma display.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
